Excellent battery isolator
After reading the negative reviews I was skeptical about the quality (without a reason to be). Well made and does the job perfectly. I believe a lot of the negative comments are from people not holding the isolator tightly when installing and allowing the plastic bottom insulator to take the tightening torque and then breaking. You MUST HOLD THE ISOLATOR TIGHTLY IN YOUR HAND WHEN APPLYING TORQUE TO THE POST CLAMP AND THE ISOLATED POST, NO EXCEPTIONS.The other issue I read was the post clamp broke. Mine didn't, in fact the opening was sized correctly for the NEGATIVE POST AND THE ISOLATOR SHOULD ONLY BE INSTALLED ON THE NEGATIVE BATTERY TERMINAL, NEVER THE POSITIVE.No exceptions to that. You always break the negative side of the battery, NEVER the positive side because breaking the positive side will produce a spark and can cause the battery to explode if it's gassing off which it will do when charging or discharging.Far as I'm concerned the Isolator switch is a quality made component. I see no detractions in quality and if you follow my instructions, the install will be without issues.

A nice switch. I installed it on my yard truck ...
A nice switch. I installed it on my yard truck that never goes out on the road and does plenty of sitting during the year especially the summer. This should save the battery. Seems to be made well. I coated the whole thing with dielectric grease to prevent any corrosion. Was a breeze to install. Plenty of hood clearance with this model as it opens horizontally. Installed on a 1972 Ford F-250 4x4.
